摘要

为了探索具有铰接构造的多幅框架式曲线梁桥地震损伤特性，本文通过OpenSees地震工程分析平台建立该类型桥梁的非线性动力模型，应用非线性时程分析研究该桥型的地震反应特征，探讨了结构整体布置和主梁转动惯量对该桥型框架整体振动过程及桥墩损伤程度的影响；同时建立橡胶支座的弹塑性剪切失效模型，探讨了桥台支座的破坏形式。研究结果表明：在地震荷载下，非对称的多幅框架式曲线梁桥各幅框架振动不一致；桥梁两侧较矮墩的墩顶和墩底的地震反应最大，容易产生钢筋屈服现象；桥台处的橡胶支座纵向变形较大，有发生剪切失效破坏的可能。桥墩的对称布置有利于各个框架间的整体振动；主梁转动惯量极大地影响较高墩横向地震损伤的程度。

Abstract

In order to study multiple-frame style curved girder bridge with hinges, a nonlinear dynamic model of this kind of bridge is established by OpenSees program, the seismic response of the bridge is researched by nonlinear time history analysis. The impact of the form of structural arrangement and mass moment of inertial on girder to the overall vibration process of frames and the damage degree of columns is discussed. And the failure form of abutment bearing is studied through elastoplastic shear failure model of rubber bearing. The research results indicate that: under earthquake load, frames belongs to unsymmetrical multiple-frame style curved girder bridge vibrate inconsistently, the seismic response on the top and the bottom of shorter columns on both sides of bridge is largest, and this response can easily make the steels here yield, the rubber bearing at the abutment is possible to fail because of the large longitudinal shear deformation. It is beneficial for frames to vibrate together when the height of columns is symmetric arrangement. Mass moment of inertial on girder influences the transverse seismic damage of longer column greatly.
